Tunable Consistency in Apache Cassandra refers to the ability to adjust the level of consistency for read and write operations. By default, Cassandra operates at a consistent-local level (CL), meaning that a write operation will return once it has been acknowledged by the coordinating node. However, users can choose from multiple consistency levels, such as: 1) One - waits for a write to be acknowledged by one replica. 2) Quorum - requires acknowledgement from more than a simple majority of replicas. 3) Any - returns immediately after the coordinating node has accepted the request.
